Dell EMC Solutions Enabler 9.2 SRDF Family CLI User Guide

Setting up multi-hop manually

1. Wait for any ongoing establish to complete.
2. Split the BCV pairs (2b in Figure 1):

   symmir split -g newdg2 -rdf -remote
   

   The -remote option specifies that the remote SRDF pairs establish.

3. Wait for the establish to complete.
4. Suspend the remote SRDF pairs (2c in Figure 1), and establish the BCV pairs (2b in Figure 1):

   symmir establish -g newdg2 -rdf -exact
   

5. Use either a device file or the -rrbcv option to establish the BCV pairs in the second hop (2d in Figure 1):

   symmir establish -f 2nd_hop_devs.txt -sid SymmID

   or

   symmir establish -g newdg2 -rrbc
   

   NOTE:

   To use the -rrbcv option, the SRDF BCV devices must have been previously associated with the group, using symbcv -rrdf

6. Wait for any ongoing establish to complete.
7. Split the 2nd hop BCV pairs:

   symmir split -f 2nd_hop_devs.txt
   

   or

   symmir split -g newdg2 -rrbcv
   

   Perform Steps 5 and 7 when you want to use the final hop 2 BCVs in the replicate cycle.

   Optionally, use the -preaction and -postaction options to specify scripts for symreplicate to run before and after splitting the BCVs (step 2).

   NOTE:

   You may have to include additional command options in some of the above steps (such as establish -full for BCV pairs without relationships).
